Indiana Jones is an American film character, archaeologist, and adventurer featured in a series of popular movies. The film Raiders of the Lost Ark (1981), set in 1936, introduced Dr. Henry (“Indiana”) Jones, a young professor of archaeology and history at fictional Marshall College, whose extracurricular activities include grave robbing and swashbuckling and whose one great fear is snakes. In the film, he seeks to recover the biblical Ark of the Covenant ahead of the Nazis, who believe that possession of this object will give them superhuman powers. In later films, Jones dodges a bloodthirsty cult, thwarts a Communist plot, and reunites with his estranged father in a shared quest for the legendary Holy Grail.
